WHlFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 403,364, dated May 14,1889.

Application filed February 28, 1889. Serial No. 301,580. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. MURPHY, a citizen of the United States ofAmerica, residing at Lowell, in the county of Kent and State ofMichigamhave invented certain new and useful Improvements inIVhiflietree- Hooks; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

My invention relates to certain new and use ful improvements inwhiflletree-hooks.

The object of my invention is to provide means whereby the trace-hookscan be quickly and securely attached to the whiffletree-hooks withoutliability of becoming misplaced; and my invention consists in theconstruction and combination of the parts, as will be hereinafter fullyset forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of myimproved whiffletree-hook, and Fig. 2 is a'plan view.

A refers to a ferrule, provided with an openended box, I), the upperwall of which is provided with a key-hole slot, 0. An eye or loop, cl,is cast with the rear part of the ferrule, and through this loop passesand freely plays a ring, D, which has formed integral therewith a hook,E, the end of which is provided with a knob or ball of such a diameterthat it may be passed through the opening in the upper wall of theopen-ended box. The free end of this hook, upon which the ball or knobis formed, extends beyond the forward portion of the ring D. It isproposed to make the ferrule of a single casting, theoutwardly-extending walls and the eye (Z being all formed integral.

It will be observed that the front end of the box I) is open, so thatthe end of the hook will have free play therein, as well as a slightvertical movement, and in practice I propose to provide the eye d with aslotted opening to permit the ring to have a slight rearward movementtherein, so that when there is pressure upon the hook the ring will bedrawn slightly forward and bear against the ferrule at the end of thewhiflietree, so as to locate the ball on the end of the hook a slightdistance in front of the enlarged portion of the key-hole slot.

The ring D is of sufficient diameter to permit it to be swung over theend of the whiffletree.

To attach the trace-eye so that it cannot be accidentally detached, itis only necessary to pass it over the end of the hook and then swing thehook above the projecting plate or upper wall of the box, when it can bepassed through the slot, when the trace will be securely maintained inposition.

The hook and ring may be either formed of one continuous piece of metal;or the hook may be rigidly attached to the ring.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is-

1. The combination, with the ferrule A, provided withforwardly-extending walls, the upper wall being provided with a key-holeslot, and a swinging hook secured to the ferrule, provided on its endwith an enlarged portion adapted to pass through the key-hole slot tolocate the end of the hook within the openended box, substantially asshown, and for the purpose setforth.

2. The combination, with a ferrule having horizontal and vertical wallsb, which project forwardly from said ferrule, the upper wall beingprovided with a key-hole slot, 0, and a swinging hook secured to theferrule so as to encircle the end of the whiflletree, the end of thehook being extended rearwardly beyond the forward portion of the ringand provided with an enlarged end, substantially as shown, and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM H. MURPHY.
